Explanation:
The answer is B), a landslide.
Answer:
14g
Explanation:
assuming that N2 is a gas, use the gas formula ( mole = volume/24) to find the number of moles
then once you have found the moles (0.5 mol) use the (mole = mass/mr) formula to find the mass
so, 0.5 x 28 = 14g
Answer:
Solution given:
2 Al + 3 H2SO4 – Al2(SO4)3 + 3H2
2mole +3mole. --- 1 mole + 3 mole
27×2g. +3×98g-------- 342,g. + 6g
we have
2 mole of Al gives. 6g of h2
5 moles of Al gives 6/2×5=15g of hydrogen
15 g is your answer
